Help me get an air pocket out of cooling system

I decided to go with a Mazierre electric water pump when I put the new engine in my Duster. The block has been filled. I filled the radiator Thursday morning and fired the car up. The water flowed very quickly thru the radiator.

Today I fired it up and set the timing. I took a look and my temp guage was up to 150. It is about 99* today but I knew there was a problem. I removed the radiator cap and sure enough, no flow in the radiator. I can hear the pump running.

I drained the radiator and refilled the motor thru the upper radiator hose. Started the pump and no flow again. Then after about 15 seconds I heard a burp sound and there was a gush of water. It stopped again but 10 seconds later there was another burp and a gush of water. It did this 5 times and then no more water flow.

I let it cool for a few minutes and tried it again. This time no flow. I squeezed the top radiator hose closed for about 10 seconds and there was a gush of water and a little flow. I noticed some bubbles in the water. After doing this about ten times I noticed that after the gush of water there would be a little flow then there would be another gush about 10 seconds later. I repeated this process for about 10 minutes with the same results.

Am I correct in assuming that I have an air pocket somewhere? If so, how do I get it out.

Thanks,

Raul

i have the Mezzaire reverse flow & it always misbehaves like this after i've drained the radiator. i found raising the back of the car is enough to get the pump to pick up & start the flow. i do a few 30 sec stops & restats to make sure all the bubbles get picked up & moved on. once it's done it's good to go for the rest of the season.

Lossen top bolts with pump on, let the air out until all you see is water, tighten back up. I have to do it all the time when I drain the water out.

This is what I did to fix mine years ago..

Notice reservoir tank.


Chris..

Get a radiator pressure tester,pressurize it at 20-25 lbs for 24 hours. That is about the best way I have found to get all the air out. If you don't have one you can get one from Autozone on their loan a tool program.

I have a Meziere, any time I drain the system I just refill it with this tool and I'm on my way.

My Mezzaire will do this too. I just remove the top left side small allen head bolt from the pump that holds it to the pump housing, it bleeds out and then it picks up the water.

LONG AGO I TAPPED A BLEEDER SCREW INTO THE VERY TOP OF THE PUMP HOUSING

Or you can fill with water. Turn pump on take air hose and GENTLY blow through the overflow hose while holding your hand where the cap goes.
